judas9r 914 Posted November 14, 2023 Was given this Ricoh Commander as a non runner. Popped a battery in it, hey presto it ticks away and chrono function seems to work fine (need reset). However having never owned a Ricoh or a four button quartz chrono, I have no idea how to set the time on the thing. Do any of you knowledgeable types out there in watch land know where to look for a basic tutorial on one of these? Unfortunately, Ricoh seem to make a printer with the same serial number so I'm getting little joy from that. Anyhow, I don't even know how to properly describe this type of chrono with only four pushers? Any help at all would be greatly appreciated. Cheers guys.

FudgyDocker 3,504 Posted November 14, 2023 Maybe, while you had the back off, look at the movement reference number and look up the movement instead? It may be used in multiple watches and you'll have more luck that way. I wouldn't mind betting that, as it's Japanese, that it may be a Seiko or Miyota movement. Can't see Ricoh doing their own movement, not being a big watchmaker. Also, Citizen are big on complex quartz movements. 1 Share this post Link to post Share on other sites

austinsom 47 Posted November 15, 2023 (edited) This looks similar to my Eco-drive. You use the bottom right crown to move the sub-dial at 6 o'clock between 'TME' and 'CHR'. When on time, pull it and it should move out a notch. The hands may move, I can't remember, but you should then be able to use one of the other crowns to advance the time. I can't remember which, but my eco-drive allows one on the buttons (think it is top right) to advance and another, maybe bottom left, to wind the time back. If I remember, I'll check my eco-drive later to confirm, but that is my recollection! Oh, and similar for the chrono. set to 'CHR' in same way then you can select which hand with one of the pushers (again, I can't remember which ) and use one of the other pushers to step the hands back and forward until zeroed. If you pull the crown and it falls out, it's not my fault Edited November 15, 2023 by austinsom Share this post Link to post Share on other sites
